Hello,
If we have a BAD block thats marked BAD and a block from reserved area is allocated to take over this marked BAD block , That kinda Byte it has in header , Do we have to find RBA table and figure out what block was reallocated and what reserved block is allocated .The BAD block will surely have a different header value right ,what about Reserved block thats now allocated inlieu of This BAD Boy .

SDD does not have a G-sheet.
Bad pages are simply excluded from work, and a new page is taken from the reserve.

Hello,
BAD Blocks Are Marked Bad ,This means they will have a header byte different from rest of the headers right ,then will the reserved block allocated to substitute this block have normal header or it will have something different and we need to read RBA table for this

There is no substitute.
as reassigned, any good page + reserve is used.
And bad pages are excluded from the workspace.
How exactly, a bunch of options, a general sheet of bad pages, or additional.
